Anza-Borrego State Park at Split Mountain. You enter on Split Mountain Rd. across fromm Ocotillo Wells OHV area, Fish Creek Wash is a main wash that has over 20 finger washes that go off too so many historical indian sites, wind caves, sandstone caverns, fossil beds in the badlands, mines etc. It is quite a unque place.
Thanks for the info. We travel out to Anza Borrego Desert SP almost every year for the wildflowers. We usually drive up Coyote Canyon to Sheep Canyon to camp for a couple of days. We'll have to go look for Fish Creek and Split Mountain.
you wont regret it.. I will take a pic of my my map I picked up from the ranger station there to give a clear idea and perspective of where its located.
